Frequently
Asked Questions

A standard backwater valve installation typically costs $2,500 to $3,300 at Drain Ridge. We confirm the exact price after an inspection and free estimate.

Yes, the City of London and the City of St. Catharines offer programs that cover part of the cost of an eligible backwater valve. Both programs require approval before work begins, so apply first and schedule the installation after you receive confirmation.

No, a backwater valve only stops sewage from flowing back from the municipal sewer. Groundwater leaks through walls or the floor need drainage solutions, such as weeping tile and a sump pump.

We recommend checking the valve at least once or twice a year, including before the spring thaw. Regular checks keep the flap moving freely so it can close when needed.
